SHIRT-STU D.

SPECIFICATION forming part of Letters Patent No. 473,336, dated April 19, 1892.

Application filed September 29, 1891. Serial No. 407,161. (No model.)

To all whom it may con/cern:

Be it known that l, MILTON E. OPPENHEIM- ER, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Improvement in Shirt-Studs, of which the following is a speciication.

My invention relates to a shirt-stud wherein the two main parts are pivoted together and adapted to be moved in opposite directions and swung on their pivot, so that in one position said parts are in line and the back part can be inserted through the eyelet-holes of a shirt and in the other position, after insertion in the shirt, said parts are swung at right angles, so as to be held in place in and connected to the shirt. I employ a skeleton setting, adapted to hold a precious stone or some other desirable form of ornamental head for the stud, and I connect therewith a post, This post is pivoted in and to the partthat forms the back of the stud, which part is preferably of tubular form and slotted longitudinally to provide for the movement of the pivoted parts in bringing them into line or at right angles. I prefer aform of construction wherein the back is made of a slotted tubular body and contains a longitudinally-movable stem to which the post is pivoted and which stem passes through a collar in the tubular back and has a head at its inner end and between the collar and head, and around the stem is a helical spring to retract the stem. The post and stem are at right angles to each other when in a normal position, and are to be moved in opposite directions and swung into line when it is desired to insert the stud into the shirt or to remove it therefrom.

In the drawings, Figure l is an elevation and Fig. 2 a longitudinal section and partial elevation at right angles to Fig. l of my improvement in a normal condition, the dotted lines showing-the stud as ready for insertion in the shirt. of my invention.

The shirt-stud is shown upon a greatly-enlarged scale.

ce represents the skeleton setting or head to the stud; b, the post connected therewith. The post b is pivoted at 2 to one end of a stem c, thatris movable longitudinally and centrally within the slotted tubular body d,

Fig. 3 illustrates a modification which forms the back of the stud, and the inner end of the stem c has a head e itting within the tubular back d. The post b can be moved in the slot of the tubular back d and the stern to which it is pivoted is drawn along with it lengthwise of the back CZ. f represents a collar, fastened in said tubular back, and the stem c passes through the collar and around said stem. Between the head e and collar f is a helical spring h, which acts to retract the stein and its pivot to near the head f and nearly midway between the ends of the tubular back d and with the post Z9 at right angles to the cylinder d. This is the position that the stud occupies normally or after being inserted into a shirt.

To remove the stud from or insert it into the shirt, the setting or head and the tubular back are grasped in the ngers and pulled in opposite directions, and the setting or head and its post are swung around into line with the tubular back until the post passes into the slotted tubular back and the setting rests upon and is held against the end of the back bythe expansive action of the spring. In this position the stud can be readily inserted into or removed from the shirt, and this is facilitated by the knob or eye 3, that I have shown and prefer to employ at one end of the tubular back d. l

The post of the setting may be pivoted at 2 to a short stem c', Fig. 8, and the helical spring 7i be fastened at one end to the tubular back d and at the other end to the short stem, the spring contracting to the normal position and being extended when the setting and post are brought into line with the cylinder-back.

In my improvement the post b passes into the back cl, and the pivotal connection to the stem being within the tubular back d does not come into contact with the falbric, and the the latter is drawn away from the ornamentel head ct suiieient for the end of the tubular back to move clear of the two or more thicknesses of fabric around the post b, and 5 the pivotal connection within the slotted tubular back serves to limit the movement of the tubular back upon the post both laterally and longitudinally, so that the parts cannot be separated and the spring cannot be unduly 1o strained.

I Claim as my invention- The combination, with the tubular back slotted at one side and end, of the stud head and post, the latter passing through the slot of the tubular back, a stem and helical spring, x 5 and a joint between the stem and the post, such joint, stem, and spring being within the tubular back, substantially as set forth.

Signed by me this 24th day of September, A. D. 1891.
